A friend of mine, whom I go to college with will soon spend a few days at my house. I have noticed that recently he has become more distant (not intentionally, that's just the way it has worked itself out). An observation that I have made is hat while we enjoy each other's company, he like's my sense of humor and I can keep him entertained, sometimes if we are together for an extended period (like for a long trip), after a while I can't think of anything to say. Sometimes silence is good. But, too much is bad. I think that he is the type of person who wants me to make sure that I can keep him entertained if he can't think of anything to say (but not to the point where I am talking so much that I am annoying).
Part of my problem is that since our school is so small, and since we started at the same time, we are together for a lot of things anyway so it really doesn't make much sense to ask about things that are going on in his life (except at home, and he keeps alot of that to himself).
So my question is, does anyone have suggestions about things to talk about to kill a dead silence with someone that you are already close too, and can talk about a number of things with already but seems bored (and in turn becomes more attracted to people that can better entertain him) sometimes. NB: I think he might have ADD.
